By this, suppose the starting thread is "abc" and if the user replies to this thread even by using different name in subject like "def", then also it will fall under the same thread.
To get it done, we will have to decompose the database 1 into 2 parts, One mapping Message_IDs to Threads,we will need to keep one of these records for every message, not just every user/thread as someone may well reply to not the last post by a user. (we can let them expire after a given period of time) 1.user_id | msg_id | thread_id Second the users activity on a given thread, the second thus only needs one record per user-thread) 2.user_id | thread_id | count One way to bypass this system is by composing new mail. This can also be avoided to an extent if we provide limit on the number of new threads one can start on the list.
